Little League elbow is a condition that is caused by repetitive throwing motions, especially in children who play sports that involve an overhand throw. "Little Leaguer's elbow" was first coined by Brogdon and Crow in an eponymous 1960 article in the American Journal of Radiology. The name of the condition is derived from the game of baseball; it is most often seen in young pitchers under the age of sixteen. The pitching motion causes a valgus stress to be placed on the elbow joint which can cause damage to the structures of the elbow, resulting in an avulsion of the medial epiphyseal plate (growth plate). The first diagnosis of the injury in 1960 set off a firestorm of controversy regarding how much youth baseball players can and should be asked to pitch. The ailment even appeared in the comic strip ''Peanuts'' in 1963 when Charlie Brown received a diagnosis. In 2007, in order to protect against overuse injuries, Little League Baseball began limiting the number of pitches a player could throw per day.〔(【引用サイトリンク】url=http://www.littleleague.org/Page56025.aspx )〕 Adult pitchers do not experience the same injury because they do not have an open growth plate in the elbow. Instead, in adult athletes a more common injury is to the ulnar collateral ligament of the elbow, an injury that often requires Tommy John Surgery in order for the athlete to resume high-level competitive throwing. ==See also== *Tennis elbow *Golfer's elbow *Repetitive strain injury *Radial tunnel syndrome *Panner disease 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Little League elbow」の詳細全文を読む スポンサード リンク
